The Castle hillfort, scheduled monument in Dorset

What is recorded here

The Castle on Castle Hill combines two different ancient works: an older burial mound and a later fort overlooking the River Frome. The fort's broad scarp surrounds level ground, while the mound survives inside it as evidence that this hill mattered long before the defences.

Who made it and when

A community probably made the burial mound sometime between about 2400 and 1500 BC. Different people enclosed the hill between the eighth and fifth centuries BC. The mound was already old when the fort was raised, although the surviving evidence does not explain how the later builders regarded it.

How it was made and used

The fort builders shaped a single steep scarp around an oval area of about 1.7 hectares, using the hill itself rather than cutting a visible ditch. Raised strips of ground formed gates on the north-west and north-east. Earlier workers had piled up a round burial mound with a surrounding quarry hollow.

What was found

No excavation result or ancient object is named in the account. The order of the two works is understood from their forms and usual dates: the round burial mound belongs to a much earlier tradition than the lightly defended hilltop enclosure around it.

What remains

A seven-metre-wide scarp, reaching about 3.5 metres high, outlines the fort around a level interior. The flat-topped burial mound measures about 18 metres across and 1.6 metres high. A small southern cut has disturbed it, but its buried outer quarry line is expected to remain.

Why it mattered

The hill commands the Frome valley and preserves two choices to mark the same prominent ground, separated by many centuries. Reading the mound and fort together can show how burial, memory, gathering and defence became attached to an enduring place in the landscape.
